Thank you for your reply, Mark_R.  I realized that I was entering information into the Notes Field to the right of the Sales Receipt entry form (see attached Screen shot).  The lower red arrow points to the Notes Field I used initially.  I entered the Notes in both the Customer Tab and the Transaction Tab. I was unable to print those notes on the Sales Receipts.  Then I found the other Notes Field in the 'Customize Template' screens, so I added that field to my Screen and Print versions of the Sales Receipt.  Success -- That Notes field appeared correctly (see upper red arrow) on my screen and in print, but the field has a 30 character limit, which does not work for me.  Is there any way to print out the other Notes field, which doesn't appear to have a character limit?  There is also a field in the Footer tab, called Long Text, but that won't work, because it can only be printed and does not appear on the screen.

Adding a transaction-specific note to a sale receipt (or to any form for that matter) would be very helpful.
